If you like the look of fuller lips but aren't interested in permanent or semi-permanent cosmetic procedures, a little makeup can do the trick. Whether your lips lack pigmentation or are naturally uneven — with one side looking bigger than the other or the top lip looking smaller than the bottom — you can use the following tips. These will help you achieve a fuller and more even lip look, while still looking believable.
Things You'll Need
Lipstick or tinted lip balm
If your lips are very thin and you want them to appear fuller, avoid dark lip colors and stick with subtle shades for a more natural look.
Step 1: Create a Smooth Base
When using makeup to make your lips look fuller, it is important to start with smooth, soft lips. Exfoliate your lips by gently rubbing them with a cotton swab and some lip balm (use a rich, conditioning one). Remove all dead skin (any loose, flaking skin) and then remove excess balm from lips with a clean cotton swab. Your lips should be soft but not greasy or slippery from the balm
Step 2: Fill In and Define Your Lips
Fill in your lips entirely with the lip liner. Cover any lack of pigmentation in your lips. Read more on ehow.
